The present invention provides a method of making a metal complex. The method comprises the steps of: (a) acylating a dipyrromethane or a 1-monoacyldipyrromethane to form a mixed reaction product comprising a 1,9-diacyidipyrromethane; (b) combining the reaction product with a compound of the formula R

in the mixed reaction product, wherein D is a 1,9-diacyldipyrromethane; and then (c) separating the metal complex from the mixed reaction product. The method may be utilized for the convenient synthesis and separation of 1,9-diacyldipyrromethanes. Metal complex intermediates useful in such methods are also described.
1,4-Phenylene-bridged [26]hexaphyrindimer 3 was synthesized by the condensation of 1,4-phenylene-bridged tetrapyrrole carbinol 7 with tetrapyrromethane 8. The dimeric structure of 3 was confirmed by X-ray analysis. 1H NMR spectroscopy revealed that 3 and its [28]hexaphyrin congeners 4 exist as conformational mixtures in solution. Such conformational dynamics were found to be frozen for their RhI complexes

series of novel bis(dipyrromethanes) with versatile arylene linkers through an indi- um(III) chloride-catalyzed condensation reaction between various dialdehydes and pyrrole has been developed. This protocol is applicable to constructing a variety of bis(dipyrromethanes) with diverse functional linkers, which provides a powerful route to construct libraries of functionalized porphyrin dimers and even
